DAVID GUELBAUM, OF SYRACUSE, NEW YORK.

GRAIN-CUTTING MACHINE.

Application filed October 21, 1922. Serial No. 596,176.

T 0 all whom t may concern.'

Be it known that I, DAviD GUELBAUM, a citizen of the United States, anda resident of Syracuse, in the county of Onondaga and State of New York,have invented a certain.

` new and useful Grain-Cutting Machine, of

which the following is a specification.

My invention of a grain cutting machine has for its object the cuttingup of cereal grains, such as wheat, rye, barley, into particles, coarseor fine, without cracking or crushing of the grains and without powderedwastage, so that the cuttings obtained are less exposed to the dryingdeodorizing atmospheric action and the nutritive essence of the grainsis better preserved, than in other grain disintegrators, and such cleancereal cuttings are therefore better adapted for dietary purposes,especially for the makin of bread from un-milled cereal grains. yinvention comprises the above set forth novel features, embodied incombinations and constructions as hereinafter set forth and claimed, andas illustrated in the accompanying drawings, in which similar charactersdesignate the same corresponding parts in all the views.

Fig. 1 is a vertical section of my grain cutting machine.

Fig. 2 is a cross section of the same, show- .ing the cutting edges. y

iig. 3 shows the adaptation of the machine to a belt drive with variablespeed.

Fig. 4 sho-ws a modification of the inner cutting cylinder, providedwith a separate cutting sheet steel cover.

As seen on Fig. 1, my grain cutting machine consists of the grain hopper1 having an offset cylindrical flanged top 2 and an open tapered flangedbottom with a supporting ledge 3 inside. Into that ybottom of the hopperis fitted in the stationary o-uter cylinder 4 resting on the ledge 3 andsecured by the tap bolts 5. By loosening these bolts the cylinder 4 caneasily be taken out and replaced by another one to suit different kindsof grains when desired.

This stationary outer cylinder 4 is provided with longitudinal slotswith beveled o.' edges, as shown on Figs. 1 and 2; the` solid strip 6 inthe middle of the cylinder, shown on Fig. 1, serves merely as are-enforcement. i Y

. Inside the stationary outer cylinder 4 is tted slidingly the innerrotary cutting cylinder 7, provided with similar longitudinal slots withsharper beveled cutting edges, as Shown on Figs. 1 and 2.

The top of the inner cutting cylinder 7 fits into the bottom of the coneshaped cover 8, shown in section on Fig. 1, and is held securely by thetap bolts 9; by loosening these bolts the cutting cylinder can easily betaken out and replaced by another one when desired. The rim 10 at thebottom of the cover 8 loosely overlaps the top of the stationary outercylinder 4 to protect it from injury, as shown on F 1.

The cone shaped cover 8 terminates at its top with the shoulder 11 andprojecting pivot on which is keyseated the hub of the handwheel 12 andsecured by the tap bolt and washer 13, as shown on Fig. 1. This handwheel is provided with the radial arms 14 and the circular rim 15resting on the ianged oifset 2 on top of the grain hopper 1 and fittingslidingly into same. The rim 15 of the hand wheel is held fast to itsseat by several clips 16 bolted on to the top iange of the hopper, asshown on Fig. 1. j

Thus, the hand wheel 12 carrying the cone shaped cover 8 with thecutting cylinder 7 is reliably supported and guided, taking off all sidestrains from the cutting cylinder.` By un-fastening the clips 16, thehand wheel 12 with the cover 8 and the inner cylinder 7 can be bodilytaken out vof the grain hopper 1. i

On the arms 14 of the hand wheel, near its rim 15, are cast on tl'ebos'ses17, to one of which is fastened ,the handle 18 for rotating thehand wheel. i To the bottomof these bosses 17 are fastened the scoops orstirrers 19, consisting preferably of twisted plates, as shown on Fig. 1and in section on Fig. 2. These scoops,rotated by the` lhand wheel, inthe direction shown in plan Fig. 2, shovel and thrust the grains throughthe longitudi-` nal slots of the outer stationary cylinder 4, thegrains'being met and "cut by the sharp cutting edges of the rotatinginner cylinder 7. l

One'of the clips 16 holdingthe handwheel fast to its seat isprovided atyits top with the button headed setscrew 20, piercing through slightlyinto the rim 15 of the handwheel, for they purpose of holding thehandwheel fast to the hopper, when the machine is not working, in suchal position, that the strips of the innercylinde'r 7 cover the slots ofthe outer stationary cylinder 4i, and no grains'can pass through theslots. c

The grain hopper 1 is mounted with its bottom flange on top of thewooden box 21, provided with the drawer 22 inside, for collecting thedischarged grain cuttings, as they drop off the inside surface of thecutting cylinder 7.

The action of the machine is as follows: Vhen the machine is not workingand the hand wheel 12 is held fast by the button headed setscrew 20, thestrips of the inner cylinder 7 cover the slots of the outer cylinder 4L,and no grains can pass through. rIhe hopper 1 is then filled with grain,the hand screw 2O is loosened and the hand wheel rotated by the handle18 in clock wise direction, as shown in plan on Fig, 2. rffhe rotating'scoops 19 shovel and thrust the grains through the longitudinal slotsof the stationary outer cylinder et, the projecting and passing grainsbeing met yand cut by the rotating` cutting knives of the inner cylinder7.

By loosening the fastening bolts of the scoops and turning them to theposition shown in dotted line 19 on Fig. 2, the direction of rotation ofthe hand wheel may be reversed to opposite clock wise motion, and theopposite cutting edges on the inner cylinder are then utilized.

lThe more cutting knives are passing per minute over the slots of thestationary outer cylinder, the finer evidently will the cuttings be.Therefore, by rotating` the hand wheel 12 faster or slower, the obtainedgrain cuttings will accordingly be finer or coarser, as desired.

Fig. 3 shows the top portion of the machine adapted for a belt drivewith variable speed. For that purpose the projecting pivot on top of thecover 8 and the hub of the hand wheel 12 are extended upward, and a steppulley is key seated and setscrewed on the extended hub.

F ig. 4f shows amodification of the inner cutting cylinder. Instead ofthe cutting c knives being cast inl one with the cylinder,

the latter one is provided with the thin sheet steel cover 24, made inone piece, or in segments, and fastened to the outer surface of theinnercylinder by, countersunk setscrews,

or soldered on, the sharp edges on thev slots of the sheet forming thecutting knives, which can thus 'be removed kand re-sharpened, orreplaced by new ones, as desired.
